TYPEWRITING MACHINE.

Application filed January 23, 1926. Serial No. 83,286.

This invention relates to typewriting machines equipped for continuous fan-fold billing, and particularly to a novel folding hair die for the manual operat on of the carboncarrying frame.

In the well-known Underwood fan-fold typewriting machine, the carboncarrying frame is provided with a handle to manually return the carbon-carrying truck to re position the carbon-sheets from the typed section of the web to the following section next to be typed upon.

This invention is especially adapted to be used in connection with a device such as disclosed in the patent to Smith, No. 1,358,033, of November 9, 1920, in which an Underwood fan-fold typewriting machine is arranged for the alternative use of any one of a plurality of webs which is placed when not in use in a container at the rear of the machine.

When it is desired to change the web so as to feed to the machine a different type of form, the web, together with the carboncarrier and its associated carbons, is removed from the carbon-carrier truck and is placed in a container at the rear of the machine. Heretofore the handle has been rigidly fastened to the carbon-carrier atright angles thereto, and owing to the fact thatthe handie is. comparatively long and the carrier is also long and narrow, it forms an angular structure which is difficult to handle and which does not fit the container very well.

One of the features of this invention relates to the provision of a handle for the manual operation of the carbon-carrier, which handle may be folded parallel to the frame when not in use, thus providing a compact structure which is detached from the machine and is placed in a storage container together with the unused portion of the web.

Another feature relates to novel means for locking the handle in its operating position. Said means are manually releasable to permit the folding of the handle for storage.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a plan view of a carbon-car'- rier truck and a detachable carbon-carrying frame with the foldable handle in operative position and locked.

the web-form 14, with interleaved carbonsheets 15, being fed around the platen, not shown, the carbonsheets being secured to blades 16 mounted on the carbon-carrying frame. The truck is then manually returned by means of a handle 17 secured to the frame.

In changing a web-form, its interleaved carbon-sheets and carbon-carrying frame are detached from the machine with the web and the unit stored in a container for future use.

The handle 17 at the rear end is secured to one leaf 18 of the hinge member 19 so it can be swung from its operative or extended position (Figure 1) to a folded position longitudinally of the frame (Figure 3). The other leaf 20 of the hinge member is secured at 21 to a bracket 22 rigidly attached by means of bolts 23 on the usual left-hand side of the carbon-carrying frame.

The handle is securely held in the opera tive position by means of a latch 2 1 pivotally mounted at 25 on the upper end of the bracket 22, slot 26 in the latch fitting over a shouldered stud 27 positioned at the rear end of the handle. The latch is provided with a finger-piece 28.

Means are usually provided in the Underwood machine for expeditiously removing the frame 11 from the truck 10. Said means include a pair of pins 34 fast to the frame 11, which pins enter into holes in the truckplate 29, thereby doweling the frame in place. In order to prevent the accidental displacement of the frame 11, the pins 3 1 are provided with slots 30 for receiving latches 31, which are pivoted at 32 upon the truck plate 29. By; means of this simple arrangement the frame may be separated from its carrying-truck by simply swinging the latches 31 away from the pins 34;, by means, of tabs 33 struck out of said latches.

' Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others,

Having thus described my invention, I

claim: A

1. A handle for the manual operation of the carbon-carrying frame of a fan-fold typewriting machine, said handle being swingable from the operative to acomp'act position parallel to the frame, means including a bracket for attaching said handle to the frame, the handle being pivotally mounted on the bracket, and means for holding saidhandle in its operative position, the

holding means being manually releasable to permit swinging of the handle to itsinopera tive or folded position.

2. The combination in a fan-fold typewriting machine having a platen and a detachable carbon-carrier, the latter being arranged to reciprocate toward and away from the platen, and a handle for operating said carbon-carrier, said handle being foldable ina compact-compass so as to form with the carrier a compact unit for detachment and storage.

3. The combination in a fan-fold typewriting machine having a platen and a carbon-carrier, the latter being arranged to reciprocate toward and away from the platen,

a handle for operating said carbon-carrier,

of small compass, and means for locking said handle in its operative position, v

5. The combination in a fan-fold typewriting machine having a revoluble platen and a carbon-carrier-truck arranged to be moved toward and away from the platen, said truck supporting a carbon-carrier 'd-etachably mounted thereon, said carbon-carrier having a handle for the manual operation thereof, said handle being foldable in a compact form upon the carbon-carrier, and

means for locking the handle in its operasaid carrier, said handle being pivotally' mounted on said bracket and'beingwhen in 1ts operating position in a plane perpendicular to the platen, and said handle being foldable in a direction along the platen, so as to form a compact unit with the plate, easy to be stored when detached.

7. A carbon-carrier for afan-fold' typo- Writing machine having a platen, said carrier including a long narrow plate upon which carbon-blades are mounted, the longestdimension of said plate being parallel to the platen, a bracket fast to said plate at one side thereof, a handlefor the manual opera tion ofsaid carrier, said handle being pivotallymounted on saidbracket and being when in its operating position in a plane perpendlcular to the platen, and said handle being foldable in a plane parallel to the longest dimension'ofthe plate, so as to form a compact unit, easy to be stored, and'means for locking the handle in its operating position, said means including a latch pivotally mounted upon said bracket and a stud fast to said handle, said latch being designed to engagewith said stud. so as to prevent the swinging of the handle.
